Implication

Quantum simulation reveals emergent hydrodynamic universality classes in a 51-ion spin chain, indicating how macroscopic transport emerges from nonequilibrium quantum interactions.

Key Points

To experimentally determine whether classical hydrodynamic transport universally emerges in the nonequilibrium dynamics of a long-range interacting quantum system.
Engineered an interacting spin chain using 51 individually controlled trapped ions.
Measured space-time-resolved spin correlation functions initialized in an infinite-temperature state to evaluate quantum transport.
Observed a continuous spectrum of hydrodynamic universality classes ranging from conventional diffusion to anomalous superdiffusion characterized by Lévy flights.
Extracted macroscopic transport coefficients directly from experimental dynamics, linking hydrodynamic behavior to underlying microscopic spin interactions.
